stuff they use, quote:
'
In this paper, we develop an approach based on readily prepared and
cheap Eu3+-containing polyoxotitanium cages (Eu-POTs) which, we show,
possess the necessary design features listed before.
Having established the ground rules for selective modification,
we introduce a working prototype luminophore with high PLQY (>60%)
which is soluble in a range of commercial plastics, including
water-based acrylic paint that can be sprayed onto conventional glass
greenhouses in an agricultural environment.

Greenhouses will never grow much of the world's needed food.
 
But things keep getting better:

More CO2 is part of the reason, which is why people pump CO2 into
greenhouses.

My dear fellow, did you not suggest only a short time ago that we both
ignore this OP's off-topic nonsense?  Just a little reminder....
